Specification of Letters Patent.

Patented July 30, 1907.

Application filed May 19,1906. erial N 317.833-

To all whom all. may concern:

ie it known that I, Enema \Vsns'rnu SUMMERS, of \\*'ilkinsburg, in thecounty of Allegheny and State of Pennsylvania, have. invented a certainnew and useful improvement in tars, of which improvement the followingis a specification, reference being had to the ac.- companyingd rawings,forming partol' this Specification, in which; i

Fig. l is a vertical cross section taken in line l1. in Figure 2.

FigfZ is a partial longitudinal section taken in a vertical plane nearthe center line of the car, as in li ne' 2-2 in Fig. 1.

Fig. 3 is a vertical cross section taken in the same plane as Fig. l,but with the doors shown opened to the center.

Fig. 4 is a sectional plan view taken in line 44 in Fig. 1.

Fig. 5 is a plan view ol' the chain guide and hinge cen tering devicefor the outside door supporting chains.

Fig. (3 is a side elevation of hinge centering device, showing a portionof the door and taken in line (56 in Fig. 5.

My invention relates to the class of cars having drop bottoms fordischarging the load and is designed to provide a simple and ellicientmeans of discharging the load all in the center between tracks or alloutside of rail on either side and to spread the load when dischargedbetween the rails or to push it outward when discharged outside of therails and thereby prevent the material from falling on the track andobstructing the pathway ol' the wheels,

The arrangement of the car and of the doors and door mechanism designedalong lines brought out in my Patent No. 778,384, Dec., 27th. 1904. Someof the improvements in this present application being, lst., the hingecentering device for the outer edge of the doors. 2nd, the lender platesat the ends of the doors for the prevention of an overflow of materialat the ends when the doors are lowered and for distributing andspreading the material alter its discharge. 3rd, the throttling beamsfor checking the liow and controlling the amount of low when dischargingmaterial in the center, between rails.

In the drawing, show the doors 1, the outer support-chains 2, the innersupporting chains 3, the outer hinge lug t, the chain guide and hingecentering device 5, the fender plate 6, with its sloping end portion 7,the throttling beams 8.

The door chains 2, at the outer edge of the door pass through the hingecentering device 5, and drawing the door-hinge-lug 4 with its convexsurface 9 in contact with the concave surface 10 of the centering device5, permits the inner edges of the doors to be lowered as shown in Figure3. This construction serves to retain the outer edges of the doors intheir hinge centered position, and also to permit the outer edge of adoor to be lowered as shown in Figure l, and to be returned to itsclosed position, by any means whereby the chains 2 are drawn in and letout. A means is thus provided for centering the hinge at the outer edge01' the door while the inner edge is being opened, and for releasing thehinge at the outer edge and opening that portion while the inner supportis acting as a hinge.

The hinge centering device 5 is preferably made of cast metal, but maybe made of any material.

The lender plate (5 is arranged transversely of the car, with it majorportion extending in a vertical plane and at right angles with the hingeaxes of the doors, and with its end portions 7 extending at an anglewith its major portion, and preferably in a vertical plane, the angulardirection being away from the door and the door opening for the purposeof pushing or plowing a mass of discharged material outward from the cartrack by the car moving along the track while the load is beingdischarged. I

The throttling beams 8 shown in section in Fig. 3 and in partiallongitudinal elevation in Fig. 2 are purposely omitted in Figs. 1 and 4,and extend from fender plate o near one end of the car to acorresponding fender plate near the other end of the car, the car beingby preference symmetrical in this respect about its transverse centerline. The throttling beams 8 are located at such a height above thetrack and have such distance between the beams taken transversely of thetrack that materials discharged from the car by opening the doors 1 inthe center to any position 11 as shown by dotted lines in Fig. 3 willcause the materials to lodge in some position 12 as shown by irregularlines 13 in Fig. 3, leaving the track railsiree of obstruction by thedischarged materials. The said throttle beams 8 have also a positionwhich leaves an open space between the lower edge of door 1 and the topedge of beam 8 which will permit the insertion of a bar to dislodge anymaterial that may bridge the opening and check the ilow.

For the sake of clearness the doors 1 are shown in Fig. 1 with one ofthem in its closed position and the other one in its open position foroutside dumping, but either door may be lowered or raised at its outeredge independent of the other or both doors may be lowered or raisedattheir inner edge simultaneously.

Many changes may be made in the form, arrangement and number of doors,position and shape of the hinge centering device, location or shape ofthe throttling beams, position, extent or angular location of fenderplate without departing from my invention.

I claimz- 1. In a car, a hinge member on a door which isrelensnble fromits hinging position, and a hinge centering member fixed on the car, oneof such members having a convex surface and the other of such membershaving a eoiiperating concave surface.

2. In a car, a hinge on a door which is releasable from its hingingposition, and an open sided pocket fixed on the car for centering thedoor hinge lug,

In a car, a door having a movable support for its hinge, a hingecentering device fixed on the car, the said hinge centering devicehaving an open sided pocket which is concentrically arranged around thehinge center, to permit of the removal of the hinge from the pocket.

4. In a car, a tender extending transversely of the car forits middleportion. its end portions extending at an angle between the transverseand longitudinal direction of the car, and a door opening positioned fordischarging materials to the side of the car and adjacent the endportion of the fender, which materials ma be moved outward from the carby the action of the inclined fender when the car is moved along itsline of travel.

6. In a car. a pair of throttling beams having a location under andlongitudinally of the car, and a door opening for discharging materialbetween thethroitling beams, the throttling beams being located inposition to eontrol the Ilow of the material.

7. In a car, a pair of beams located longitudinally of the car and nearthe-ear track surface, the beams being separated to permit of adischarge of material between the beams, a door opening above the beams.and a space be tween the door and beams Avhen the door is open, for thepurpose set forth.

8. In a center dumping cal ya pair of doors hinged on longitudinal axes,the doors opening at the center line of the car. a pair of beamsarranged under the door opening.

with an open space between the beams, the lower edges of the beams beingat such a height above the car track as to check the lateral flow ofdischarged granular materials and heap it away from the rails.

S1. The combination with a dump ear adapted to discharge at the side andat the center. of a tender comprising a central portion extending acrossthe car at sub stantially a right angle to the axis of the ear and anobliquely extending end portion.

10. The combination with a dump car provided at its lower portion with adoor adapted to s\vi g laterally to permit oi a discharge to-the side ofthe ear. of a fender extending across the car adjacent the end of thedoor at substantialhr a right angle to the a is oi the car and providedwith an obliquely extending end portion.

In testimony whereof, I have hereunto set my hand.
